About this 3D model

I couldn't find a stock that fit the aesthetic I wanted, so I designed my own. Here is the result. The stock has a lenght of pull of roughly 11.5" at base, but features a 25mm and a 12.5mm extension, which ideally should be printed in TPU for comfort. The stock locks in with a Magpul RSA QD sling attachment point (or clone). This locks into the picatinny on the stock, and offers a stable sling point with no reliance on print strength/quality. If you don't want/own the RSA QD, please print the "Buttstock (Bolt) version, which instead uses a metric M4 inter bolt (outer diameter of 5mm). For this version, bolt length should be roughly 31mm at max. Alternatively, an appropriate length M5 screw and nut could also fit. 2x M5x20-25mm Screws are used to attach the Buttstock attachments if used. Head diameter must be 9mm or less. Some of the mesaurements on this design were intentionally oversized to grant secure lockup, and so some minor amount of sanding/fitting may be required. Edit 22/04/2026 - Extension plate step files uploaded to allow for user customisation. Edit 26/04/2026 - Dedicated version created for bolt usage, with significant reinforcement. No longer requires adapters.
